' Appendix J - Ground Water P&T Volume-Mass Calculations <br /> • AGE-NC Project Not 95-0130 <br />' Page 3 of 3 <br />' 3) 03 May 2005 - 03 June 2005 <br /> Assumptions <br /> • A total volume of 78,160 gallons was extracted from wells EW-1 and EW-2 between 03 May <br /> 2005 and 03 June 2005 (based on effluent flow meter observations) <br /> • Data collected from the pump and treat influent were representative of general extracted <br />' ground water conditions <br />' One gallon of water is equivalent to 3 79 liters, so the volume of processed water is given by <br /> V= (78,160 gallons)(3 791/gal)=296,2261 processed water <br /> Multiplying the volume of the processed water by the average of the May 2005 and the June 2005 <br /> TPH-g concentrations(39,000µg/l)yields the approximate mass of TPH-g removed fromprocessed <br /> water <br /> MTpH_g= (296,226 Z)(0 000039000 kg/0 = 11.55 kg TPH-g <br /> 1 A converstion factor of 2 205 lb/kg can be used to convert kilograms of TPH-g to pounds of TPH- <br /> g <br />' MTPH-s = (11 55 kg TPH-g)(2 205 lb/kg) =25.47 lb TPH-g <br /> Advanced GeoEnvironmental,Inc <br />
